1 Claim.

Clothes wringers are ordinarily provided with wringer rolls which are subjected to a yielding pressure. The wringer is usually provided with means for adjusting the initial pressure on the rolls, but as different qualities of material are passed through the wringer the amount of separation of the rolls and the arrangement of springs exerting the pressure bring about wide variations of pressure. It is desirable that the operator be informed of the pressure operating on the rolls. not only initially but with relation to the various separations to which the wringer is subjected. The present invention is designed to provide means for this purpose. Features and 5 details of the invention will appear from the specification and claim.

A preferred embodiment of the invention is illustrated in the accompanying drawing as follows:

l marks the base of the wringer frame, 2 the side stiles and 3 the top bar. One end of the top bar is secured on the stiles by interlocking shoulders 4 and at the opposite end by a safety release 5, the safety release being of the type described in my application, Serial Number 621,918, filed July 11, 1932. 6 marks the lower roll, 6a the upper roll. and 1 the shaft of the lower roll which as shown is the drive shaft. The shaft 1 is journaled in bearings 8 carried by brackets 9 in the stiles. The upper roll has the shaft In which is journaled in bearings Illa slidingly m mounted in the stiles. A spring ll exerts pressure on the upper bearing blocks. A screw l2 operates through a nut IS in the top bar and is Divided and this application June 9, 1939, Serial No. 278,300.

swiveled at l2a on the spring. The screw is operable by a handle l4. These parts are, or may be, of common construction.

A movable base I5 is provided with a collapsing fluid receptacle IS. The opposite end of the re- 5 ceptacle is mounted by a clip IT on the spring. The receptacle is connected by a tube IS with a tube IQ of a fluid pressure indicator in in which the pointer 2i indicates the pressure to which the fluid in the collapsible receptacle is subjected. 10 This fluid pressure is responsive to the pressure exerted on the spring and the pressure indicator is calibrated with relation to the fluid pressures incident to pressure exerted by the spring on the collapsible container so that the pressure exerted ll by the spring on the rolls is at all times indicated on the pressure indicator.

While I have exemplified my invention as applied to wringers, I wish it to be understood that the invention extends to wringers and the like in 20 which there are squeezing rolls utilized for operating upon clothes.

This application is a division of application No. 62,606 filed February 6, 1936.

What I claim as new is: 25

In a wringerand the like having a frame, wringer rolls mounted in the frame, one of which rolls is movable, and means exerting yielding pressure on both ends of the movable roll so as to urge the latter toward the other roll, said 30 means substantially equalizing the pressure at the opposite ends of the rolls with varying degrees of movement of the roll; the combination with said means of a collapsible fluid container having a base on the frame and pressure en- 35 gagement with the means, said engagement sustaining the initial and cumulative pressure on both ends of the roll, and a fluid pressure indicator connected with the container and indicat ing the roll pressure. @0
